Tang Shuxing, who was gradually sliding down the other side of the ridge, maintained the slowest movement, because the movement of even a stone sliding down the mountain would alarm the Wehrmacht soldiers patrolling below. He had to find out what Shandu's purpose was in setting up a concentration camp here, and what they were digging for.

When sliding down the ridge, Tang Shuxing took advantage of the situation to hide in a pit dug out of the slope of the mountain, the pit was obviously dug by large machinery, and then dug by hand, but the strange thing is that the topsoil layer is all shale, and the shale crevices are very wet, and it seems that the digging can not be moved further down, because there are many damaged tools discarded around, many of which have either been bent or broken directly.

Mining? It's not like, Tang Shuxing thought about it for a long time, recalled it in his mind, and finally came up with a word - shale gas?

Shale gas is an unconventional type of natural gas that needs to be extracted from shale formations. Tang Shuxing remembers reading the news that it was first discovered and mined by the Americans, followed by Canada. Is it still necessary to collect energy and fuel from all over the world? What about oil in the Middle East? Why did they choose to mine in Europe, and it seemed that the shale around it was stronger than they expected, so they didn't dig too deep and gave up.

Tang Shuxing investigated for a while, looked down, and decided that he might as well sneak in and look inside the concentration camp to see what they were looking for here.

After making up his mind, Tang Shuxing slowly climbed down the slope, but fortunately, there were all large rocks here, and there was very little gravel. The debris had been removed, so there was no big movement when he left the hillside, but when he went down and saw the ground on both sides of the camp, he suddenly looked back at the mountain he had come down from, and realized that there was no snow at all on the mountain that had been mined!

Why is this happening? Didn't it snow just the other day? And I have touched those shales before, although it is wet, but it is not so hot. How come there is no snow at all?

Tang Shuxing felt that this mountain was even more strange. After infiltrating the concentration camp, I felt into a nearby warehouse and looked at the equipment in it, all of which were old-fashioned. It seems that in addition to the large excavators. The people here mined the stones by smashing. There is not even the most fundamental electric stone crusher. Even if Shang Du wants to mistreat these captives, he should also consider not giving them advanced tools. On the contrary, it will delay the progress of the construction period.

It's not so stupid, and under the premise of large machinery, do you still need to dig manually with basic tools? Tang Shuxing didn't understand, looked at the warehouse for a while, then felt it out, and continued to move forward.

The concentration camps built along the mountains don't seem to be worried that such mining will lead to landslides, probably because the weather is too cold and the snow freezes all day long. After walking for less than ten minutes, I suddenly saw countless soldiers standing in front of the rows of prisoner barracks, and then the horn sounded in the camp, calling the prisoners to get up and work.

Tang Shuxing looked at the time, it was 10 o'clock in the evening, what did it mean to come out to work during this time period? He turned to the side of the house and pricked up his ears to listen, and then the barracks door opened, and countless prisoners streamed out of it, yawning, most of them complaining, but complaining about the concentration camps, which made them sleep during the day and work at night, for some reason.

Sleeping during the day? Working at night? Tang Shuxing was even more puzzled, and he couldn't understand what Shang Du was doing in this place at all.

Tang Shuxing decided to follow the captive brigade to see where they went to work, and then the captives began to collect their tools one by one, a team of 20 people followed a Shangdu Wehrmacht soldier towards the distance, everyone's expressions were sluggish and numb, a little tired, but it didn't seem like they had been completely brainwashed, but it could be seen that no one had the will to resist, and seemed to fully accept the qiē they had experienced.

After walking a hundred meters with the captive brigade, Tang Shuxing, who was lurking in the dark, saw them enter a cave like a train tunnel in the mountain next to them, and there were two rows of soldiers standing at the door, searching them, not even their nostrils, ears and eyes, and the big sign next to them said in Chinese and English that they were not allowed to carry anything such as lighters, matches, and other objects.

Tang Shuxing wanted to go in very much, but he knew that it was impossible at the moment, because it was too easy to expose himself, and if he didn't say anything, his future plan would be completely defeated.

"Let them hurry." At this time, Xia Jiezhu walked to the entrance of the cave and said to a trembling officer next to him, "This time your time is only half a month, Lord Gu has been very lenient with you, and you have said all the good things in front of Lord Creation, otherwise, you would have been the same as your previous one." ”

The officer kept nodding his head, wiping the sweat oozing from his forehead on this cold night.

Although Tang Shuxing was far away from them, he could clearly hear the conversation between the two of them, and Xia Jiezhu seemed to deliberately raise her voice so that others could also hear it, so that they could understand the severity of the matter.

"If, after half a month, the test finds that there is indeed nothing we want, then this place must be abandoned." After Xia Jiezhu saw that most of the captives had already entered the cave, she spoke again, turning her head slightly to look at the officer.

The officer looked at Xia Jiezhu suspiciously: "My lord, but, judging from the detection in previous years, there should be zài 'compressed gas' here, right?" ”

After the officer said the word "compressed gas", Xia Jiezhu immediately glared at him and said word by word: "I've said it many times, don't say those three words, it's highly confidential!" ”

The officer realized his mistake and immediately bowed his head, and was about to kneel down at the sight of it.

Compressed gas? What's that? Unheard of, a new source of energy? Tang Shuxing didn't understand it at all, but decided that since she couldn't enter the cave, she just found a way to get close to Xia Jiezhu, she couldn't stay in this place all the time, right?

Xia Jiezhu then entered the cave, and came out again in a few minutes, coughing constantly, it seemed that the air in the cave was not good, the officer followed behind her, Xia Jiezhu waved his hand to let him stare at the cave, and he walked straight towards his own residence next to him, Tang Shuxing followed Xia Jiezhu's side, followed her to the outside of the residence, and then climbed to the second floor from the rear, originally planned to sneak in from the second floor, who knows, just climbed to the position of the second floor, as soon as he looked up at the window, he saw Xia Jiezhu standing there taking off his windbreaker.

Tang Shuxing squatted there and looked at Xia Jiezhu, and suddenly remembered the strange dream he had when he was in New York, in which Xia Jiezhu got married, although the groom looked at him, but he was sitting in a wheelchair, what did it mean? Tang Shuxing leaned there and stared at it for a long time, and then a stone came from behind, Tang Shuxing turned around and grabbed the stone, and then looked at a man with a face full of camouflage coming out of the darkness under the house, and when he turned around, he suddenly looked surprised.

Tang Shuxing leaned down and looked at the man, and the man also looked at him, and suddenly the man smiled, and when that smile was revealed, Tang Shuxing also realized who he was—Quinn.

Tang Shuxing immediately jumped out of the room and fell to Quinn, Quinn looked him up and down, kept shaking his head, Tang Shuxing smiled at him, just when Quinn was about to speak, Tang Shuxing grabbed him and dragged him into the darkness, and pointed to the top of the mountain, indicating that this was not the place to speak, and he had to go up and talk about it.

The two of them immediately climbed up the hill and climbed to the top, and after turning over there, Quinn hugged Tang Shuxing.

Tang Shuxing patted him on the back like a child and said, "Okay, two big men don't want to be like this, okay?" ”

Quinn looked at Tang Shuxing and shook his head, "We knew you were still alive!" It seems that Solomon's operation was successful! ”

"Solomon's actions? What action? Tang Shuxing didn't know that Solomon had dragged him out of the underground fortress of the White House, let alone that Solomon had been killed by Shangdu.

Quinn was also curious: "Aren't you with Solomon?" ”

Tang Shuxing shook his head, and then recounted how he woke up on the beachhead and how he got here.

After hearing this, Quinn nodded and said, "I see, it seems that Solomon is less auspicious." ”

"How could Solomon be with you?" Tang Shuxing asked.

Quinn sighed: "7 years ago, after the ice bomb hit Washington, all the Washington area was frozen up, and the information we got was that Shangdu originally planned to use ice to suppress the ground crack, etc., who knew that the power of the ice bomb was too great, and it could not be controlled, and it began to spread like a plague in all directions, and in a few years, most of the United States was all affected." We didn't know your exact location at the time, but we thought you were in the Washington area, and to be honest, everyone thought you were finished, because Sharman Dynamics was running a satellite to scan the surface biology of the Washington area, and the news came back was that there weren't any living creatures. ”

Tang Shuxing looked at Quinn and asked, "Then how did you know I was there?" And why did it take seven years to come to me? ”

"At that time, no one knew your location, like a stone sinking into the sea, Ah Yue tried his best to collect it, and we even contacted the Gangster Federation and Ghost in the end, they all said that they had seen you, but they didn't know your whereabouts, and then Shangdu's large-scale attack began." Quinn frowned and closed his eyes, "You don't know how terrifying it is, there are many places that are not destroyed by their invasion at all, they are natural disasters, so they swept the world without much effort, and within a few years, we originally pinned our hopes on the remaining Asian and European troops, but they disappeared, rumors spread, some people say that the Asian and European forces surrendered to Shangdu, and some people say that they are hiding somewhere in the North and South Poles, waiting for the opportunity to rise again, but no one knows how the truth ......is"

In the 5th year after Tang Shuxing disappeared, Yao Lu Xiucai handed over the news that Tang Shuxing was confirmed in the original White House to Ah Yue, and told Sù Ah Yue that the news was 100% reliable, but at that time, the resistance army had already gathered forces and decided to launch a counteroffensive on the European continent, and Ah Yue also knew that Tang Shuxing's news could not be known by others, so he could only put his hope on Solomon.
